As Argentina has no military 'solution' to the FI, this is the chosen path. South America is emerging as a significant economic power house and we are on our knees. Make life difficult economically and, hence, politically. Get Brazil on side and game over really. Chile will have to do as it's told or Argentina will turn its lights off (literally).
The next 'war' has kicked off and is an economic one. We have little to fight with.
What next? An air embargo? No Casevacs allowed to land? No Diversions?
This will test 'call me Daves' political muscle. My money's on South America.
